How can I remove the excess object detected? Often my code finds more mouths and I want take only one, the one which is belower. Thanks.

FDetect = vision.CascadeObjectDetector;

I = imread ('Test W.jpg');

figure(1),imshow(I);

title ('...')

BB = step(FDetect,I);

figure(2),

imshow (I); hold on

for i = 1:size(BB,1)

rectangle('Position',BB(i,:),'LineWidth',5,'LineStyle','-','EdgeColor','r');

end

title ('...');

hold off;

NoseDetect = vision.CascadeObjectDetector('Nose','MergeThreshold',16);

BB=step(NoseDetect,I);

figure(3),

imshow(I);hold on

for i = 1:size(BB,1)

rectangle('Position',BB(i,:),'LineWidth',4,'LineStyle','-','EdgeColor','b');

end

MouthDetect = vision.CascadeObjectDetector('Mouth','MergeThreshold',16);

BB=step(MouthDetect,I);

figure(4),

imshow(I);hold on

for i = 1:size(BB,1)

rectangle('Position',BB(i,:),'LineWidth',4,'LineStyle','-','EdgeColor','g');

rectangle('Position',BB(i,:),'LineWidth',4,'LineStyle','-','EdgeColor','r');

1. Input the face to mouth and nose detection and not the complete image
2. play with threshold value

see how picutre on bottom left is cropped from top right picture and after that nose and mouth detection is applied
